TURNER FOR TIN ROOFS.

Application filed February 14, 1885. Serial No. 155,973.

T 0 aZZ 1071,0722, it may concern.-

Be it known that 1, ROBERT FRANK Snow, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Turners for Tin Roofs, of which the following is a specification.

The object of my invention is to provide a device which will support the vertical portions of thejoint and bend the partly-turneddown upper edge over the lower edge.

My improvement consists in a device comprising a grooved plate and a grooved wheel journaled thereto, the said plate adapted to press against and uphold the upright edge of one plate of metal, and the wheel adapted to uphold the upturned edge of another sheet of metal and to run over and turn down the partly-0verturned edge of the latter sheet over the edge of the former sheet, substantially as shown in the accompanying drawings, and described hereinafter.

Hy improvement consists, further, in combining with the base-plate of my device a shoe by which it is adapted to edges of different height, as hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my turner. Fig. 2 is avertical transverse section through the base plate and through a shoe therefor. Fig. 3 is a vertical transverse section of the compressing-wheel. Fig. 4: is a vertical transverse section on the line 00 m, Fig. 1,in connection with the partlyoverturned edge and vertical portions of adjoining sheets, the shoe being shown attached.

Similar letters of reference in the several figures indicate the same parts.

In roofing with tin the contiguous sheets of tin are brought together with their adjoining edges turned up, the edge of one being turned up more than the other. The edge standing highest is turned over the lower one by a seamer. At this stage of the process my turner is employed.

A is the base plate of my turner,grooved to receive the overturned edge left by the seamer. The sides of the groove are plain and at an angle to each other best adapted to the style of work to be done.

B is the compressing-wheel of my turner. It is grooved, so as to present a surface, 6, on a line with the angle (Z of the groove in the baseplate, and a flange, a, playing outside of the vertical side f of the baseplate. The base-plate (N0 model.)

is provided with an upright or standard, C, t which the wheel is journaled by means of a1 axle, h, secured to the standard.

h is a washer between the outer end of th axle and the wheel. The standard is show] cast integral with the base-plate. Rigidly at tached to the base-plate are posts or stand ards k k, to which is secured a handle, K.

H is a shoe to increase the height of th base of the turner. This shoe is shown as pro vided with a screw, N, entering a hole, N, ii the base-plate as means for connecting the sho to the plate. The shoe is shown detached ii Fig. 2, and in broken lines in Fig. 4it is show] attached.

The machine is operated as follows: Afte the higher upturned edge, 1, of one sheet, 2, i bent over the upturned edge 3 of the othe sheet, 4, by the seamer my turner is applie with the side f pressed close against the sid of the shorter upright piece, and the flange o the wheel pressed close against the longer up right piece. The wheel B runs on the top 0 the overturned edge. It will be seen that bht inside or shorter edge is held pressed up to th other upright portion against the fiange,whili the Wheel crowds down the covering part 0 the longer piece closely to the inside uprigh portion. The two upright portions, being thu: pressed closely together and standing at righ angles to the roof, are again bent over by tht seamer on a line at about half their height and my turner, the shoe being removed again pressing with its side against the upright por tion and its wheel running over the turned over portion, is used to complete the work 0 turning down. It will be seen that while thi upright part cannot bend or sway inwardly the overturned part is brought down closely on the upright part and a close joint is nec essarily made. The rib or joint is finished by running the seamer along the side of the up right rib or ridge formed by the above process I claim as new and of my invention 1. The combination of a grooved plate anc' a grooved wheel journaled thereto, the saic' plate adapted to press against and uphold thc upright edge of one plate of metal, and tl1 wheel adapted to uphold the upturned edge 0: another sheet of metal and to run over anC turn down the partly-overturned edge of th( latter sheet over the edge of the former sheet substantially as shown and described.
